BEGISTEBING MECHANISM FOR CALCULATING-MACHINES.

To all whom 'it 'may concern:

. Be it known that I, GEORGE C. CHASE, of the city and county ofProvidence and State of Rhode Island, have invented certain new anduseful Improvements in Registering Mechanisms for Calculating-Machines;and I do hereby declare the following specification, taken in connectionwith the accompanying drawings, forming a part of the same, to be afull, clear, and exact description thereof.

The present invention relates to a registering mechanism which isspecially adapted for use in calculating machines, but which may also beemployed in other types of registering machines.

The invention may be applied both to keyactuated machines and to key-setmachines and to the various forms of each of these types of machines.

The primary object of the invention is to provide a registeringmechanism which will permit two or more of the dials or numeral wheelsto be rotated simultaneously by their actuators, and which will alsopermit one or more of said dials or numeral Wheels to be actuated by thecarrying mechanism simultaneously with the rotation thereof by theiractuators and without the carrying movement becoming merged or lost inthe movement imparted by said actuators.

The inventioh consists primarily in the combination, with the numeralwheels, of planetary gearing for actuating the same, one part of saidplanetary gearing being adapted to be operated by the actuator for thenumeral wheel and the other part being adapted to be operated by acarrying mechanism embodying a spring for actuating the same. l

The invention consists in the combination, with a numeral wheel, of agear for rotating said numeral Wheel, said gear being adapted to berotated about its own axis and also about an axis not coincident withits own axis, and means embodying a spring for actuating said gear. A

The construction further consists in the combination, with the numeralwheel, of a gear for rotating said numeral wheel, said gear beingadapted to be rotated about its own axis and also about an axis notcoincident with its own axis, and means embodying a spring for rotatingsaid gear about one of said axes.

Serial No. 635,936.

The invention further consists in the combination, with the numeralwheel, of a gear for rotating said numeral wheel, said gear beingadapted to be rotated about its own axis and also about an axis notcoincident with its own axis, an actuator for rotating said gear aboutone of said axesfand a carrying mechanism embodying a spring forrotating said gear about the other of said axes.

The invention further consists in certain constructions and combinationsof parts hereinafter described and set forth in the claims.

` Referring to the drawings, Figure 1 is a side view of a registeringmechanism embodying the invention. Fig. 2 is a front View of the same,one of the numeral wheels and its adjunctive devices being shown insection. Figs. 3 to 20, inclusive, are detail views showing the severalparts, Figs. 6 to 16, inclusive, being arranged in such relation to eachother that if the parts therein shown were brought together along thecenter line,

said parts would be assembled in proper relation to constitute theorganized combination embodying the same.

In the drawing the registering mechanism is shown as applied to acalculating machine having the general construction and organization ofthat shown and described in the patent to J. A. Turck, No. 720,086,dated February 10, 1903. As the present invention relates to theregistering mechanism, only such parts of the mechanism for actuatingthe numeral wheels by the column actuators as are adjacent to thenumeral wheels are shown in the-drawings, reference being made to saidpatent to Turck for an understanding of how the parts referred to areactuated. i

Referring to the drawings, 1 is the segmental gear which is normally outof engagement with the gear 2 through which the numeral-wheel 3 isrotated. The segmental gear 1 is carried by a vertically movable bracket4 carrying a roll adapted to be engagement with the pinion 2, and thenby the further turning of the cam-gear the. projection 6 is brought intoengagement with the arm 7 and the segmental gear turned the properdistance.

In the present construction the pinion 2, instead of being rigidlyconnected to the numeral wheel 3, is connected therewith through asystem of gearing in the form of sun and planet gears. rIhe sun-gear 8is mounted on the hub of the pinion 2 so as to rotate therewith.

9 is what may be termed a sustaining gear upon which the planet-gearsare mounted, said sustaining gear being rotatably mounted on the hub ofthe pinion 2. In the drawings three planet-gears are shown, but agreater or less number may be employed, as desired. Each of theseplanet-gears is a double gear, that is, each comprises two sets ofgear-teeth, one set being adapted to be engaged by the sun-gear and theother set being adapted to engage gear-teeth on the numeral-wheel. Asshown in the drawings, each planet-gear is made in two parts 10, 10a,said parts being adapted to be secured together and each part beingprovided with a set of gear-teeth. If desired, however, the parts 10 and10a may be formed integral. These planet-gears are rotatable upon studs10b secured to the sustaining gear 9. The numeral-wheel 3 is providedwith gear-teeth 11 adapted to be engaged by the gear-teeth on the part10HL of the planet-gears, said teeth 11 constituting in eect an internalgear.

Secured to the opposite end of the hub of the pinion 2 are'tworatchet-Wheels 12 and 13, the teeth of which are oppositely arranged.'Ihe ratchet-wheel 12 is adapted to be engaged by the tooth 14 of' apawl 15, to prevent forward rotation of the numeral wheel, while theratchet-wheel 13 is adapted to be engaged by the tooth 16 of a pawl 17to prevent backward rotation of said numeral-wheel. The pawl 15 is alsoprovided with a projection 18 which, as shown in Fig. 1, is arranged inline with the upper end of the movable bracket 4, the construction beingsuch that when said bracket 4 is raised by the action of the cam-gear 5the pawl 15 will be turned about its .pivot so as to disengage the tooth14 from its ratchetvwheel and thereby release the numeral-wheel its axisto rotate said pinion, the sun-gear will be rotated with said pinion.The rotation of said sun-gear will serve to rotate the planetgears abouttheir own axes, and through such rotation of the planet-gears thenumeral-wheel 3 will be turned, it being understood that at this timethe sustaining gear 9 is to be held against rotation.

As there is never any carrying to the wheel of lowest order, thesustaining gear for that wheel may be, and preferably is, permanentlyheld against rotation. In the construction shown a pin 20 projectingfrom the frame is arranged to enter a recess formed in a boss projectingfrom one side of the sustaining gear, as shown in Fig. 2.

In the present construction the carrying from a wheel of lower order tothe wheel of neXt higher order is effected by the rotation of thesustaining gear 9, and consequently when carrying is to be performedsaid sustaining gear, which at other times is to .be held againstrotation, is to be released and rotated for the performance of suchcarrying operation, and the rotation of said sustaining gear for thispurpose is effected by means of a spring which is gradually wound up bythe rotation of the lower wheel from 0 to 9 and is then released as thelower wheel passes from 9 to 0.

Referring to Figs. 1 and 2, the carrying spring 21 is connected at oneend to a stud 22 secured to the numeral wheel 3 and has its other endconnected to a disk 23 rotatably mounted on the hub 24 of said numeralwheel. Secured to the disk 23 is a pinion 25 which meshes with a gear 26secured to a short shaft 27 mounted to rotate in a bracket 28 secured tothe frame. Secured to said shaft 27 is a pinion 29 which meshes with thesustaining gear 9.

In order that the carrying spring 21 may be wound up by the rotation ofthe numeral wheel of lower order it is necessary that the disk 23 towhich the opposite end ot said carrying gear is connected shall be heldagainst rotation while said wheel of lower order is passing from 0 to 9.For this purpose a detent-lever 30 pivoted at 31 is provided, saiddetent-lever being provided with a projectionor detent-nger 32 adaptedto engage a projection 33 on an arm 34 carried by the disk 23. Saiddetent-lever 30 is normally held in engaging position by a spring 35,one end of which is connected to the outer or upper end of saiddetentlever. The downward movement of the outer end of the detent-lever30 under the action of said spring 35 is limited by the engagement ofsaid detent-lever with the frame, the position in which said detentlever30 is thus normally held by the spring 35 being such as to hold thedetent-nger 32 in line with the projection 33, as shown in Fig. l. V".

For the performance of the carrying operation it is necessary that thecarrying spring 21 after being wound up by the rotation of thenumeral-wheel of lower order from 0 to 9 shall be released assaid-numeralwheel passes from 9 to 0. For this purpose the detent1ever30-is provided with a second projection in the form of a cam-face 36which normally lies in the path of the stud 22 carried by thenumeral-wheel The arrangement of these parts is such that as thenumeral-wheel passes from 9 to 0 the stud 22 will ride up the cam-face36, thereby depressing the lower or inner end of the detentelever andmoving the detent-inger 32 out of engagement with the projection 33 andthus releasing the disk 23, which then becomes free to be rotated underthe action of the carrying spring 21.

The rotation of the disk 23 is accom-- panied by a. correspondingrotation of the pinion 25, which serves through the gears 26 and 29 toimpart rotation to the sustaining gear 9. The rotation of saidsustaininggear has the effect to carry the planet-gears about the axisof the sun-gear and in so doing to impart a small amount of rotation tosaid planet-gears about their own axes,

thereby turning the numeralwheel of next higher order with which saidplanet-gears are in engagement one step and thus eifecting the carryingoperation from the numeral-wheel of lower order to said highernumeralwheel.

YV hen the detent-lever 30 is depressed by the engagement of the stud 22with the camface 36 said stud, as the numeral-wheel to which it isconnected continues to rotate, passes over the top of saidcam-projection 36. lVhen the disk 23 is released to be rotated by theaction of the carrying-spring 21, the projection 33 likewise passes overthe top of the detent-nger 32. Then both of `these things have happenedthe detent-lever numeral-wheel of lower order.

30 will, under the action o f the spring 35, be returned to its normalposition, and so that when the disk 23 has completed one revolution, theprojection 33 will again come into engagement with the detent-inger 32,and the further rotation of said disk 23 be thereby prevented.

If for any reason the carrying spring 21 should at any time becomesluggish in its act-ion, and so that it should fail to move theprojection 33 pastthe detent-finger 32 and to the far side thereofbefore the spring acts to return the detent-lever 30 to its normalposition, the disk 23, and thus the pinion 25, would be again blockedagainst rotation and the carrying operation would fail to be performed.To guard against this possibility means are provided whereby thenumeral-wheel of higher order will be advanced one step and the carryingoperation be performed by the direct action of the For this purpose aguard 37 is mounted on the arm 34iin position to have the free endthereof engaged by the stud 22. The arrangement of the parts is suchthat the stud 22 engages said guard 34 before said stud passes over thetop of the cam projection 36 and before the numeral wheel has moved to0, the engagement of said stud 22 with the guard 31 taking place,however, immediately after the detent-fnger 32 has been moved out ofengagement with the projection 33. 'ith this construction during thelatter part of the movement of the numeral-wheel from 9 to 0, theengagement of the stud 22 with the guard 31 serves to positively movethe projection 33 past and beyond the detenttinger 32, and so that whenthe detent-lever 3() is returned to its normal position under the actionof the spring 35 it will be certain that the projection is on the farside of the detent-finger 32. and so that the disk 23 and pinion 25 willthus be sure to be free to be rotated by the action of the carryingspring 21. If now for any reason said carrying spring, by reason of itsbecoming broken or otherwise, should fail to act, the stud 22 willremain in engagement with the guard 31, and as the numeral-wheel oflower order is again moved from 0 to 9, the disk 23 and pinion 25 willbe positively turned by the rotation of said numeral-wheel, and so asthus to positively effect the carrying to the wheel of higher order. Itis also de sirable to guard against any possible sluggishness or failureto act on the part of the spring 35 in returning the detent 30 to itsnormal position. Thus if said detent-lever 30 should not be promptlyreturned to its normal position it might notI occupy Said position whenthe disk 23 and pinion 25 had completed one revolution, with the resultthat the further rotation of said parts would not be arrested as theyshould be. ll'ith the construct-ion shown, if said det-ent-lever shouldnot have been returned to its normal position by the action of thespring 35 at the time the `disk `23 is about completing its revolution,the upper edge of the projection 33 will come in contact with the loweredge of the cam projection 36 and acting thereon, will serve topositively raise 'the inner end of the dete-nt-lever 30 and thus returnthe same to normal position.

lVith the sun and planet gear construction above described rotation ofthe planet-gears about their axes, and thus rotation of thenumeral-wheel with which said planet-gears are in engagement, may beeffected in either one of two ways. Thus said planet-gears may bedirectly turned about their axes by the rotation of the sun-gear, whilesaid planet-gears may be indirectly turned about their aXes by beingcarried about the axis of the sun-gear by the rotation of the sustaininggear upon which said planet-gears are mounted. As will be understood,the rotation of the planet-gears effected by carrying said gears aroundthe axis of the sun-gear may take place at the same time that saidplanet gears are rotated by the rotation of said sun-gear, and furtherthat any rotation of the planet-gears resulting Jfrom the carrying ofthe same around the axis of the sungear will become effective to imparta carrying movement to the numeral wheel of higher order, even thoughsaid numeral wheel is at the same time being rotated by the rotation ofthe planet-gears produced by the rotation of the sun-gear. lilith thisconstruction, therefore, two or more numeral wheels may besimultaneously actuated and at the same time the carrying trom one wheelto the other will be properly eEected and without the carrying operationbecoming lost or merged in the movement imparted to the higher numeralwheel by its own actuator.

ln the construction shown the sun-gear is arranged to be rotated by theactuator for the numeral-wheel, while the sustaining gear for theplanet-gears is arranged to be rotated by the carrying mechanism. Itdesired, however, the arrangement may be reversed and the sustaininggear arranged to be rotated by the actuator for the numeral-wheel andthe sun-gear arranged to be rotated by the carrying mechanism.
